Ferrosilicon 65 yog ib qho hlau Alloy muaj ntau yam ntawm cov hlau thiab silicon, feem ntau nrog cov kab zeb silicon ntawm}%, thiab cov so feem ntau ntawm cov kab mob uas tsis huv. Lub alloy yog nyiaj-grey, nrog lub ntom ntom ntawm kwv yees li 3.5g / cm³ thiab melting taw tes nruab nrab ntawm {5}} degree. Hauv cov ntawv thov metallurgical, cov particle loj faib ntawm Ferrosilicon 65 muaj qhov cuam tshuam tseem ceeb ntawm kev siv cov nyhuv, feem ntau xav tau} hli blocks lossis {mm granules.
Kev yug ntawm ferrosilicon 65 tuaj yeem raug taug qab mus rau kev siv hloov tshiab hauv lub xyoo pua puv 19. Nrog rau kev tsim muaj ntawm Bessemer Converter cov txheej txheem, metallurgist tau pom tias silicon tuaj yeem tswj cov pa oxygen hauv Molten hlau. Xyoo 1883, french cov tub ntxhais kawm lub cev tau kawm cov txheej txheem ntau lawm ntawm cov alloys thawj zaug, tso lub hauv paus rau kev lag luam niaj hnub ferrosilicon. Thaum ntxov xyoo pua 20, nrog rau kev txhim kho cov hluav taws xob arc rauv tshuab, ferrosilicon 65 pib tsim tawm ntawm lub ntsuas loj. Tshwj xeeb tshaj yog thaum Tsov Rog Thoob Ntiaj Teb Zaum 2, kev lag luam ua tub rog tau thov kom muaj kev kawm zoo ntawm ferrosilicon ntau lawm tshuab. Lub teb chaws nplua nuj nyob rau hauv hydroRower cov peev txheej xws li Regrosia tau coj ua tiav cov thev naus laus zis ua tiav, thaum Suav teb cov kev lag luam ferrosilicon
Daim ntawv thov cov chaw ntawm Ferrosilicon 65 yog nyob deb dhau ntawm cov neeg lub tswv yim. Nyob rau hauv cov steel steel ntau lawm, nws tuaj yeem txhim kho kev duction ntawm cov hlau ua deoxidizer; Hauv stainless hlau smatting, nws tuaj yeem txhim kho cov khoom lag luam antioxidant thaj chaw; Nyob rau hauv Cam khwb cia hlau kev lag luam, ferrosilicon 65 tuaj yeem pab txhawb cov kab mob graphite thiab txhim kho cov nqaij fluidity. Nws yog tsim nyog tshwj xeeb uas muaj kev nce ntawm cov hluav taws xob hluav taws xob tshiab, thiab ferrosilicon tau tawg rau kev lag luam siab sib nqus los ntawm cov khoom sib nqus Kev sim ntawm lub koom haum tshawb fawb pom tias ntxiv tus nqi tsim nyog ntawm Ferrosilicon 65 tuaj yeem txo cov hlau poob ntawm cov hlau los ntawm 15% thiab txhim kho kev txuag hluav taws xob. Ib qho ntxiv, ferrosilicon 65 kuj yog lub luag haujlwm tseem ceeb hauv cov hlau nplaum smelting thiab kev lag luam me me, muaj txiaj ntsig me me nrog loj siv ".
Saib tom ntej, lub ferrosilicon 65 kev lag luam yog ntsib ib lub sijhawm keeb kwm rau cov kev hloov pauv ntsuab. Nrog kev nce qib ntawm "dual carbon" lub hom phiaj, ib txwm muaj kev siv hluav taws xob muaj zog ntau zog yog qhov kev hloov ceev ntawm kev hloov pauv. Cov tuam txhab ua lag luam tau pib tshawb nrhiav txoj kev tshiab xws li hloov hluav taws xob hluav taws xob thiab siv cov hluav taws xob hluav taws xob rau cov fais fab robraces.
